EYE GLASS-MOUNTING.

Specification ofletters Patent.

Patented Sept. 10, 1912.

Application filed January 17, 1912. Serial No. 671,724.

an eyeglass]uounting, of the type inquestion, with a simple andconvenient device for supporting the coiled spring removably inoperative position. To this end 1 cmploy a slotted post adapted toreceive the coiled portion'ot the spring, with one end of'the springseated in the slot to anchor the spring, and in order to retain this endof the spring securely in place, while the eyeglass-mounting is in use,the post is provided, at the upper end of the slot, withinwardly-projecting members or lugs, these members normally overhangingand retaining the spring in the slot, owing to the angular positionassumed by the end of the spring in consequence of the torsional ac tionthereof.

Another object of the invention is to produce an eyeglass-unmetlug inwhich both the nose-clamp lever, or finger-lever, and the spring, maybemounted upon a Single post or projection, .the spring being also anehored at one end. by said post, and. being readily removable therefrom.To this end I employ a construction in which the lever in question ispivolcd upon a post, this post having a flange, outside of the lever, toconfine the latter against its ln-raring, and the post being alsoslotted, beyond said flange, to receive the end of a coiled spring whichis removably mounted upon the post.

In the accon'q'mnying (.lrawiugs:--higuro 1 is a. plan-view, on agreatly enlarged scale, of a portion 0'! an eyeglasshiollining en1bodying the present invention; Fig. 2 is a front-elevation, partly insection, showing the same parts; Fig. 3 is a side-elevation of the postillustrated in Figs. 1 and and Fig. 4 is a horizontal section, lookingupwardly, on the line 4.-4 in Fig. 3.

The invention is illust 'ated as eu'ibodicd in an eyeglass-mounting inwhich the general form is familiar. Figs. 1 -and 2 show a portion. ofthe bridge 5 and one of the lenses 6, together with lens-straps 7, lens--clips 8, and a bearing-member or body 9 connecting these parts, and allof ordinary form. These figures also show a nose-clamp lever 10 ofordinary form, provided with the usual finger-piece 11 for actuating it,and with a nose-clamp 12 carried upon its inner end.

The invention resides particularly in the post by which the n0se'-elamplever 10 is pivoted upon the bearing-member 9, and

which supports and secures in place the spring for actuating thenoseclainp lever.

The nose-clamp lever is seated-upon the upper surface of thebearing-member 9, and is pivoted. upon. a stud or post 13, which has ascrew-threaded lower extremity screwed into the bearing-member. Thispost is provided. with a flange 14: which lies just above the nose-clamplever, thus confining the latter closely against the bearing-member, andrestricting it to swinging movements in a horizontal plane. The portion15 of the post above or beyond the flange serves as a support for acoiled spring 26 of flat spiral form, by which the nose-clamp lever isac tuated. The outer end 170i this spring is in the form of a hook,which engages a vertical portion 18 of the nose-clamp lover. The innerend 10 of the spring is straight. as shown in Fig. 1. The portion 15 ofthe post is slotted inwardly from its. end, and in the slot so formedthe straight" end 19 of the spring may be readily introduced before thehooked end 17 engaged with the noseclamp lever.

A an ore of the present invention resides particularly in the meansemployed to retain the end 1!) 01'' the spring in the slot 16. To thison d the postis provided, at the upper end ol the slot, with inwardlyprojecting lugs or overhanging portions 21, which, in the illustrated(ai'llnnlilnent ot the invention, are )ro.hu:ed by cutting away orbcveling the metal at points 20 on opposite sides of the slot, as shounparticularly in Figs. 3 and 4. Accordingly, when the hooked end 17 ofthe spring is engaged with the noseclainp lever, the. resulting torsionin the spring causes the end 1.) to assume the angular position shown inFigs. 1. and 2, whereby it firmly engages the surface of the postbeneath the lugs 21., being tl'lus locked in. place by thelatter. Owingto this arrangement, the spring cannot work off from the post during theuse of the eyeglass mounting." 'VVhen it; is necessary, 'however, toreplace or repair the spring, it can be very easilyremoved by firstdetaching the hooked end 17- and then swinging the end 19 into positionto register with the upper extremity of the slot 16, so as to disengageit from; the lugs 21 and permit the spring to be withdrawn lengthwise oithe post.

The arrangement above described, in addition to the novel and effectivemeans for, locking the'spring in place, hasthe further advantage that itproduces a simple and compact arrangement-in which the noseclamp leverand the spring are both mounted upon the same post, while the spring mayreadily be removed from the post With-. out releasing the nose-clamplever from 010- erative position o m i I The threaded extremity of thepost 13 is' illustrated, in Fig. 2, as being threaded in a i right-hand(lire'ct-idn, so thatthe torsional action of the spring 16 cannot rotateand unscrew the post. Obviously,a left-hand; thread should be used Wherethe tendencyi of the spring is to rotate the post in a leftj handdirection. The use of a threaded ex-E tremity on the post is notessential, however, i I as other Well-known eXpedi-ents may be em ployedto fix the post to the bearingf member. g

I claim p p 1. An eyeglass-mounting having, in, combination, with anose-clamp and a pivotally movable lever connected therewith, a coiledspring connected, at one end, with said lever, and a post upon which thecoiled port-ion of the spring is mounted, the post being slotted toreceive the other end of the spring and having inward projections at theupper end of the slot, adapted to retain the spring on the post when itsend assumes an angular position in the slot in consequence of thetorsional action of the spring.

2. Aneyeglass-mounting having, in combination, a nose-clamp a lever uponwhich the nose-clamp is mounted, a fiat bearingmember engaging one sideof the lever, a stud, projecting from said bearing-member, upon whichsaid lever is pivoted, the stud having a flange engaging said lever onthe opposite side from the bearing-member and being slottedlongitudinally from its end, and. a coiled spring mounted on the studbeyond said flange and removable over the end thereof, one end of thespring being con neeted with said lever 'and the other end being seatedin said slot.
